Drtrde xveight of optical cotadtuctivity is calctrlated at zero tenaperattrre by exact diagotaalizationfor the two-diraaensional t-J naodel xvith the two-p;trticle tertaa, 11". For the or'dinary t-J modelxvith VVmO, the scaling of the Drvtde xx'eight D c< (>' for Sl1121lJ doping concentration b is obtained,whicla indicates anouuaalotrs dynatnic exponent zm4 of Ulae klott tratnsitiota. When TV' is sxvitchedon, tl're dynarauic exponent recovers its conx'etutiona[ xvaltre zm2. This corresponds to an incohererut-to-coheretat tratasition associated xx'ith the sxvitchitug of' the txvo-particle tr'atnsfer.
